Soaked Into Shellac Spirit On 30th October 2015

Checked On 5th November 2015. It Peeled Slightly.

I was suggested by Mr. Alam Tunggal NurPutih to sock the suspicious items with olive oil for a few days. Then he told me to use a brush to clean the items. If the items are forgery, the outer layer will be soften and can be removed easily. The inner part is a skeleton of a cockerel that was made of lead. The outer layer is likely to be coated with fine sand.

Checked On 5th March 2016.

Later, I was briefed again by Mr. Alam Tunggal NurPutih that he found out that the caveat emptors are using the 3 seconds quick dry super glue applied on the skeleton of the cockerel perched with rings that was made of lead then rolled against the dry powder of river mud.

I was offered by the consignor to do the experiment. The suspicious items were delivered to my Dickson Niew Collection shop.
